Sensitivity to Auditory Velocity Contrast [PDF]
Scientific Reports, 2016 AbstractA natural auditory scene often contains sound moving at varying velocities. Using a velocity contrast paradigm, we compared sensitivity to velocity changes between continuous and discontinuous trajectories. Subjects compared the velocities of two stimulus intervals that moved along a single trajectory, with and without a 1 second inter stimulus

Contrast sensitivity at high velocities [PDF]
Vision Research, 1982 Measurements were made of the contrast required to see the direction of motion of drifting gratings (Part 1) and of moving bars (Part 2). The spatial frequency at which least contrast is required to see sinusoidal gratings decreases as their velocity increases, but peak sensitivity is identical at all velocities up to 800 deg/sec.

Multiple-crystal X-ray topographic characterization of periodically domain-inverted KTiOPO4 crystal [PDF]
, 1995 A periodically domain-inverted KTiOPO4 crystal has been characterized for the first time by multiple-crystal multiple-reflection x-ray topography. The striation contrast within the domain- inverted regions has been revealed in high strain-sensitivity ...

Neonatal Contrast Sensitivity and Visual Acuity: Basic Psychophysics
Translational Vision Science & Technology, 2018 Purpose This research was prospectively designed to determine whether a 0.083 cycles per degree (cy/deg) (20/7200) square-wave stimulus is a good choice for clinical measurement of newborn infants' contrast sensitivity and whether the contrast ...
